Abstract

PURPOSE:To shorten the waiting time required until switching to a facsimile terminal is performed when a transmitter completes dial operation, by performing the confirmation of telephone number information, which is dialed by a transmitter and to which multiple address is sent, in parallel with the reception of message information. CONSTITUTION:A transmitter A dials a calling telephone number from a telephone set 1 after dialing a discriminating number for communicating facsimile multiple address. Then, a switchboard 7 searches the switchboard 8 of the called person B and sends the telephone number through a line 18. The switchboard 8 checks whether the called number is stored in a subscriber file 10 and answers the result to the switchboard 7. The switchboard 7 confirms the answer and connects the subscriber line 15 with a facsimile processing device 11, and then, sends the call information to the transmitter. When the button of a terminal 3 is depressed, a message is stored in a message file 13. To the called person B, the call information is transferred from the device 11 to the device 12 through a digital line 17. The transferred information is stored in another message file 14.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a store-and-forward system, particularly a broadcast communication system for transmitting the same information to a plurality of destinations in a facsimile store-and-forward system.

In this type of conventional broadcast communication method, telegram information is delivered to the recipient using destination phone number information specified by the caller through dialing, etc., but when the caller specifies destination phone number information that does not exist. In order to prevent messages from being undelivered, when the network received the destination telephone number information from the caller, it first confirmed whether the destination party was a subscriber to the network before starting to receive the message information. Therefore, the caller has to wait from the end of the dialing operation until the network completes confirmation of the destination, and especially in the case of broadcast communication with a large number of destinations, the waiting time is very long, resulting in poor service quality and poor subscriber service. In order to solve these drawbacks, the present invention enables confirmation of destination telephone number information and reception of message information in parallel.The drawings are described in detail below. explain.

The figure shows an embodiment in which the present invention is applied to a facsimile communication system, in which 1 and 2 are telephones, 3 and 4 are facsimile terminals,
5 and 6 are switchover devices between the telephone set 1 or 2 and the 7 axis terminal 3 or 4, respectively, and normally the subscriber line 15.
16 has been switched to telephone 1 or 2. 9
．． Reference numeral 10 constitutes a subscriber information storage means, which is a subscriber file for storing information on subscribers subscribed to the network in association with telephone number information, and reference numerals 7 and 8 indicate dial input from telephone set 1 or 2. A subscriber line exchange that receives and analyzes data information, controls the reading of subscriber information from the subscriber file 9 or 1o, and 13.14 is a message file for temporarily storing message information, which is a message storage means. can be,
11.12 receives the message information from the facsimile terminal 3 or 4, stores the message information in the message file 13 or 14, controls the calling of the telephone 1 or 2, transfers the message information to the facsimile terminal 3'' or 4, etc. A facsimile processing device that performs processing, 15.16 is a subscriber line, 1
Reference numeral 7 indicates a digital line connecting the facsimile processing devices 11 and 12, and 18 indicates a signal line connecting the subscriber line exchanges 7 and 8, respectively.

In this configuration, when caller A dials the identification number for facsimile circular communication from telephone 1 and then one or more destination telephone numbers, subscriber line exchange 7 analyzes the destination telephone numbers for each destination, and , and sends the destination telephone number to the subscriber line exchange 8 via the signal line 18. The subscriber line exchange 8 checks whether the sent destination telephone number is subscribed to the network or the subscriber information stored in the subscription file 10, and sends the result back to the subscriber exchange 7 via the signal line 18. Return to. When the subscriber line exchange 7 confirms that one subscriber in the destination telephone number is a subscriber to whom delivery is possible, the subscriber line exchange 7 transfers the subscriber line 15
is connected to the facsimile processing device 11 and sends call information such as the destination telephone number to the facsimile processing device 11. Then, the 7-axis processing device 11 sends a special signal to the subscriber A, and the switcher sends the special signal to the facsimile terminal 3.
is connected to the subscriber line 15. Then, when the subscriber A presses a communication start button on the facsimile terminal 3, the message is sent as a facsimile signal to the facsimile processing device and stored in the message file 13. During this time, the subscriber exchange 7 confirms the remaining destination telephone numbers, and as soon as the confirmation is made, the processing device 1 sends the call information such as the destination telephone number by facsimile.
Send to 1. When the facsimile processing device 11 receives all the messages and finishes storing them in the message file 13, it disconnects the loop of the subscriber line 15 and delivers the messages to each destination telephone number. To the recipient B, the facsimile processing device 11 transfers the message information and call information such as the destination telephone number to the facsimile processing device 12 through the digital circuit #1117, and the factor z IJ processing device 12 transfers the message information to the -H message file. 14, the message information is stored. Next, the facsimile processing device 12 calls the subscriber B on the called party's side via the subscriber line exchange 8, the subscriber line 16, and the telephone 2 using the destination telephone number, switches the disconnection switch 6, and connects the facsimile terminal 4. The subscriber line 16 is connected to the subscriber line 16, and the message information is extracted from the message file 14, converted into a facsimile signal, and output to the facsimile terminal 4 through the subscriber line 16.

By employing these three methods, it is possible to shorten the wait time for the caller from the time the caller completes the dialing operation until the caller receives a special signal for switching to a facsimile terminal.

As explained above, by confirming the telephone number information dialed by the caller and receiving the telegram information in parallel, from the end of the caller's dialing operation until receiving the special signal for switching to the facsimile terminal. This has the advantage that the waiting time for callers can be shortened regardless of the number of broadcast destinations, providing better service for callers and increasing the efficiency of network use.
